| Object-Inertial Tracking for Human Assembly of Acoustic Timber Walls |
|
Augmented Acoustics combines the computational design of an acoustic timber wall with a novel augmented reality in-situ assembly method.
To improve acoustic qualities in the cafeteria of Basler & Hofmann in Esslingen, Switzerland, three acoustic walls with a total area of 90 m2 have been computationally designed and built. The walls are composed of 8500 identical fir timber blocks. To improve the speech intelligibility each timber block has a unique position and orientation based on the principals of the Schroeder Diffusor. Due to the asymmetric cut of the front side of the blocks, the different orientations of the blocks create customized shadow patterns on the wall, dynamically changing throughout the day. The varying gaps between the blocks in the bond improve the acoustic absorption and function as air ducts for the ventilation system integrated behind the walls. Gramazio Kohler Research and the Robotic Systems Lab at ETH Zurich have developed an augmented object laying technology, which provides visual guidance for the builder to place blocks in accordance to a specified design. The carpenters are equipped with a custom-built camera controller unit, while feedback is provided via a monitor. The system recognizes and tracks objects and provides feedback on deviations between the built structure and the virtual design.
